IPC: G01M99/00
Filed: 1982-10-29
Abstract: PURPOSE:To enable a quick and highly accurate detection of a resonance frequency of a mechanical vibration in a DC motor with a simple construction by acquiring a signal component with the frequency corresponding to the mechanical vibration from a contactless sensor output. CONSTITUTION:When a circuit is closed, a signal equivalent to the addition of a random signal and DC component is supplied to a stator 19 of a DC motor 11 via an amplifier 30. With the random signal, a mechanical vibration is excited in the motor 11. After outputted from a coil 23 of a contactless sensor 24, a signal SC with a large amplitude is supplied to an LPF34 and a BPF37 separately. The LPF34 outputs a signal component SD to be converted into a square wave signal SE. On the other hand, the BPF37 outputs a signal SI to a peak detector 39 through a frequency analyzer 38. The detector 39 detects as resonance frequency fN the frequency at the point where the level of the signal SI exceeds the reference value LT. This enables a quick and highly accurate detection of the resonance frequency of a mechanical vibration with a simple construction.

Abstract: PURPOSE:To shorten time from the selection of music to the start of play by fetching a musical score data parallelly to the transmission of a series of play data. CONSTITUTION:When reception interruption is accepted based on the transmission request of the musical score data from a host system 4, a CPU 14 preserves a required state, afterwards sets a write address pointer WAP of a musical score data buffer DBUF and returns the state after storing the musical score data in an area designated by the pointer WAP. It is preferable for this reception interruption processing to be executed for the unit of the fixed number of data transfer words so that the CPU 14 can not be occupied for a long period by the processing because time for one time transfer is prolonged so much. The music designation of the musical score data to be required on the side of an electronic instrument is applied through an input/output device 20 to a host system 2, and the host system 2 transmits the musical score data corresponding to the designation.
